JeDI has been designed as an open-access database for all researchers, media and public to use as a current and future research tool and a data hub for general information on jellyfish populations. With this resource, anyone can use JeDI to address questions about the spatial and temporal extent of jellyfish populations at local, regional and global scales, and the potential implications for ecosystem services and biogeochemical processes.

JeDI is a scientifically-coordinated global jellyfish database housed at the National Center for Ecological Analysis and Synthesis (NCEAS) , currently holding over 476,000 quantitative, categorical, presence-absence and presence only records on global jellyfish populations spanning the past two centuries.

What is the Jellyfish Database Initiative (JeDI)?

JeDI is currently undergoing final modifications and conversion to a new open-access platform to be launched soon. Information on how to deposit new jellyfish datasets into JeDI or for urgent requests to access data can be obtained by an email request to:

The successful development of the first global-scale database of jellyfish by the Global Jellyfish Group was due, in large part, to the incredible generosity of members in the international jellyfish and wider scientific communities.

Funding for JeDI and the Global Jellyfish Group came from:
